As a guitarist it’s very easy to work out the sequence of sharps and flats because of this.Took me a while to figure that the fourths and fifths of the scale get you help you figure the sharpsand flats I think...
They down in 4ths for the sharps, so you start with F# is 1st string fret 2, then C# is down one string (2nd string fret 2, up two frets for G# and D#, up two frets for A# and E#, up two frets for C#.
For flats they go up in 4ths, so start with Bb 11th fret 2nd string, up a string to Eb, down two frets for Ab and Db, down two frets for Gb and Cb, down two frets for Fb.
Then if you know the rules for naming a key from its sharps or flats you’ve got a mnemonic for all the major keys on two strings of your guitar. (Sharp keys - the last added sharp is the M7 of the key, so the key name is a semitone higher. Flat keys - you just need to know one flat is F, after that the name of the key is second last flat in the key signature.)
